Title:
SOUND PRODUCTION DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/115826
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a sound production device and an electronic device. The sound production device comprises a magnetic circuit system, a vibration system and a housing, wherein the magnetic circuit system is provided with a magnetic gap; the vibration system comprises a conductive diaphragm, a conductive support chip, and a voice coil, which is used for driving the conductive diaphragm to vibrate; the conductive support chip is arranged on the side of the conductive diaphragm that faces the voice coil; one end of the voice coil is connected to the conductive support chip, and the other end of the voice coil is suspended in the magnetic gap; a first conductive structure is provided on the conductive support chip; a second conductive structure is provided on the conductive diaphragm; a voice coil lead of the voice coil is electrically connected to the second conductive structure by means of the first conductive structure; the conductive diaphragm is arranged on the housing; a third conductive structure is provided on the housing; and the second conductive structure is electrically connected to an external circuit by means of the third conductive structure. By means of the embodiments of the present application, a new power supply mode is provided for the voice coil in the sound production device, such that a defect caused by direct electrical connection between an existing diaphragm and a voice coil can be effectively overcome.
